Question

A Copper flask with volume of 200 cm³ is filled to the brim with olive oil. If the temperature of the system is increased from 10 ⁰C to 40 ⁰C, how much oil spills from the flask?

Answer 1

Let's ,

  The coefficient of expansion of olive oil is= =0.68×10^-3 k^-1

The coefficient of expansion of copper  =17×10^-6 k^-1

The change in temperature is,

As the system is heated, both the flask and the oil expand.

The change in volume of the olive oil:IS

then,

The change in volume of the flask:=

  

[ ]

The difference in volume expansions is the volume of oil that spills out:

  

oil spills from the flask is 3.77 cm³
